Is there water in the spray powder? Why?
No, there is no water in the electrostatic powder used for powder coating. This is because powder coating relies on **dry powder particles** that are electrostatically charged and sprayed onto a surface. The powder adheres to the surface through this electrostatic attraction. Once applied, the coated item is cured in an oven where heat causes the powder to melt and form a durable, uniform finish.
Water is not involved in the process because it would interfere with the electrostatic charge and the powder’s adhesion. Instead of water, powder coating uses **polymer resins, pigments, and additives** in a fine powdered form【10†source】【11†source】.
